Has Octopus Energy beaten the price cap?

Intelligent Octopus Flux has beaten the price cap in 24 of the last 24 complete months in London.

Each month is costed both ways on the same consumption, in the same region, on a direct debit basis, with standing charges included on both sides. A month counts only when we hold every day of it.

Your postcode is sent once to Octopus Energy’s public region lookup — the same one they bill from. We do not put it in the URL, analytics or database, and do not keep it.

Month by month against the cap

On the ordinary household, single-rate meter profile at 2,500 kWh a year, 2024-10-06 to 2026-11-05. “Under” means the tariff cost less than the cap that month; “partial” means we do not hold the whole month and it is not counted either way.

How a month is decided

The tariff’s real half-hourly prices are weighted by when the ordinary household, single-rate meter profile uses electricity, then costed at 2,500 kWh a year with its standing charge added. The cap is costed identically, using Ofgem’s published unit rate and standing charge for the same region and quarter.

One consumption figure is used across the whole series on purpose. Ofgem’s own benchmark consumption changed twice in this window, and following it would show jumps that were never price movements.

A month where we hold fewer than every day, or where no cap covers the whole month, is shown but not counted. “We cannot say” and “it did not beat the cap” are different answers and the table keeps them apart.

The profile is an assumption about when electricity is used, not a measurement of your home. If you have your own half-hourly data the smart-meter replay costs your actual readings instead.
